PENClL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 307,613, dated November4, 1884-.

Application filed April 516, 1884.

To all wh0m--it may concern.-

Be it known that I, JOHN WILLIAMSON, a citizen of the United States,residing in the city and county of Camden, State of New Jersey, haveinvented a new and useful Improvement in Pencil-Sharpeners, whichimprovement is fully set forth in the following specification andaccompanying drawings, in which- Figure l is an end View of apencil-sharpener embodying my invention. Fig. 2 is a side elevationthereof. Fig. 3 is a top or plan View thereof, a portion being brokenaway and shown in section.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a convenient, serviceable, and inexpensivepencil-sharpener, as will be hereinafter fully set forth.

Referring to the drawings, A represents a blade, which is secured to astock or holder, B, the latter having a handle, 0. The blade is formedof a piece of suitablemetal, sheetsteel preferred, bent or depressed inthe direction of its length, forming a channel, a, and having both ofits ends cut diagonally and sharpened, forming V-shaped cutting-edges b.The handle 0 is properly grasped and the end of a pencil presented tothe cutting-edge b, opposite to the handle, and drawn against the same,whereby the sides of the edge out the end of the pencil uniformly atopposite places and in pointed form. By turning the pencil the entiresurface of the same will be subjected to the action of the cutting-edge,whereby the pencil will be pointed or sharpened in a regular anddesirable manner. During the sharpening operation the pencil is guidedand sustained on the base of the channel a, whereby it moves true and isprevented from displacement from the channel a, so that when the cut ismade the pencil may be pushed back on the channel, locating the point inadvance of the cutl l I (No model.)

ting-edges, ready for the next advance motion against said edges. Theholder B is channeled, as at B, between the blade and handle, so thatthe adjacent end of the blade projecting into said space is uncovered,and may be used for sharpening purposes similar to the outer end of theblade, thelatter end projecting beyondthe outer end of the holder. \Vhenthe cutting-edges are broken, worn, or dull, the screw cis loosened, andthe dull blade may be removed and sharpened or the broken and worn bladereplaced by a new one. The upper face of the holder is depressed toaccord with the under face of the blade A, whereby the sides of thedepression of the holder embrace the sides of the blade, and thus asingle screw, 0, is sufficient to prevent motion and displacement of theblade. In the holder are openings d d, which are adapted to receive pinssecured to a slate-frame, so that a scholar may connect the sharpenerwith the slate, the sharpener being readily removable therefrom andadapted'to be placed in the pocket, asv is evident. The sides of theholder are coated with emery, sand, or other suitable substance, formingrough or gritty surfaces for purposes of finely pointing the pencils,&c.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A pencil-sharpener consisting of the holder B, having a coating ofgritty substance, and a V-shaped depression to receivethe V-shaped bladeA, sharpened at both ends, one end of the blade projecting beyond theouter end of the holder and the other end into the channel B between thedepression and handle 0, the said holder being provided with openings (1d,

adapted to be attached to aslate-frame by pins,

substantially as and for the purpose set forth.
